Day 3 embryo transfer versus day 5 blastocyst transfers: A prospective randomized controlled trial
OBJECTIVE This study aimed to show whether transferring day 5 embryos resulted in higher implantation and pregnancy rates than transferring day 3 embryos in Turkish women undergoing an intracytoplasmic sperm injection (ICSI) cycle. MATERIALS AND METHODS A total of 190 women who had ICSI after retrieval of more than four oocytes on the day of fertilization check were randomly assigned to under...
متن کاملThe Pregnancy Outcomes of Day 2 versus Day 3 Embryo Transfer: A Cross-Sectional Study
Background The objective was to evaluate whether extending the embryo culture period from 2 to 3 days would yield a more optimal selection of viable embryos, thereby increasing the pregnancy rat. MaterialsAndMethods We have retrospectively analyzed pregnancy rates in the patients who had embryo transfer either on day 2 (582 patients) or on day 3 (387 patients) post-insemination over a 10-month ...
متن کاملDay 3 versus day 5 embryo transfer: a prospective randomized study.
Transfer of embryos at the blastocyst stage has been associated with exceptionally high implantation rates. There are, however, only a few prospective randomized studies comparing day 3 versus day 5 embryo transfer. Furthermore, the number of embryos replaced in the day 3 group transfer is often higher than the number of blastocysts replaced, thereby affecting implantation rates. A total of 118...
متن کاملA prospective randomized study: day 2 versus day 5 embryo transfer.
BACKGROUND This randomized controlled study was performed in an unselected IVF/ICSI population to test the hypothesis that blastocyst transfers result in higher clinical pregnancy rates (CPR) per oocyte retrieval when compared with day 2 transfers. METHODS Blind randomization for transfer on day 2 (group 1) or day 5/6 (group 2) was performed before stimulation. Oocytes and embryos were cultur...
متن کاملOffice microlaparoscopic intrafallopian transfer of day one zygote versus day three embryo transfer after previous failed ICSI trials.
The objective of the study was to investigate whether transferring zygotes on day 1 would result in similar pregnancy rates compared to transferring cleavage stage embryos on day 3 in a prospective randomized trial, using the office microlaparoscopic procedure. Patients undergoing IVF/ICSI treatments were randomized to either day 1 or day 3 transfers after previous failed ICSI trials due to fai...
